ABSTRACT:
A bicycle brake device has a pair of brake mechanisms for applying a braking action to a rim of a bicycle wheel. Each brake mechanism includes a mounting member which is fixedly coupled to the frame of the bicycle. Each brake mechanism further includes a brake arm, a linkage assembly, a brake shoe and a biasing member or return spring. In the preferred embodiments of the present invention, the linkage assembly is a four-bar linkage assembly in which a biasing member applies a stabilizing force to the links to reduce vibrational movement therein. In one embodiment, the biasing member is a torsion spring fixed about the pivot pin between the brake shoe attachment link and the brake arm. In a second embodiment, the biasing member is a torsion spring positioned between the inner link and the brake shoe attachment link. In a third embodiment, the return spring acts as both the spring for biasing the brake arm from the braking position to a release position as well as a biasing member for applying a stabilizing force on the linkage assembly to reduce vibrational movement of the linkage assembly.
